  Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the drawings referred to in the following description, the equivalent parts to the other drawings are indicated by the same reference numerals.

(Outline of face recognition system)
The face authentication system according to the present embodiment is a system for authenticating an attendee by face authentication technology when entering a specific area where only a specific person can enter, such as an event hall such as a concert hall. In order to perform face authentication, it is necessary to register in advance the face image of the attendee in the face authentication system. In the face authentication system according to the present embodiment, registration of a face image is performed in advance in the vicinity of a specific area such as an event hall before entry is started. For example, it is assumed that face image registration is performed in the same building as the event hall.

(Configuration of face recognition system)
FIG. 1 is a diagram showing an example of the configuration of a face authentication system according to the present embodiment. In the face authentication system according to the present embodiment, face authentication is performed on the attendee, but as an example, it will be described on the premise that the attendee has performed the application procedure for admission in advance. For example, on a website for application for admission, an enterer performs application procedure by inputting user data such as name, address, and telephone number in advance. The site that has accepted the application stores, for example, the user data of the applicant in the form of a database or the like in the server device of the site.

  The face authentication system 1 illustrated in FIG. 1 includes an attendee information storage unit 102, a registration photographing unit 104, an authentication photographing unit 106, a collation unit 108, an issuing unit 110, and a result output unit 112. .

  The attendee information storage unit 102 stores face image data of an authorized person who should be permitted to enter a specific area such as an event hall. For example, not only the person who applied for admission properly but also the person who received the authority to enter properly from those who applied for admission properly (for example, the procedure for changing the participants to the event) Can be applicable. In addition to the face image data of the authorized person, the visitor information storage unit 102 holds user data such as the name, address, and telephone number input at the application site at the time of admission application as described above. May be

  FIG. 2 shows an example of data stored in the visitor information storage unit 102. As shown in FIG. In FIG. 2, a user ID (identification information) for uniquely identifying an attendee, a name of an attendee (applicant), an address, a telephone number, and a file name of face image data are associated in a database format. Further, the face image data of the file name shown in the “face image data” column of FIG. 2 may also be stored in the attendance information storage unit 102. For example, if the visitor inputs information such as name, address, telephone number other than face image data online, for example, at the time of admission application, a user ID uniquely assigned such information in a format as shown in FIG. 2, for example Along with the entry information storage unit 102. Also, if, for example, the participant in the event is changed or the admission authority is transferred to another person after the change, for example, the name of the new participant for changing the participant online When the information such as the address and the telephone number is registered, the contents of the "name", "address" and "telephone number" fields in FIG. 2 may be changed.

  Prior to entry into the specific area, the registration imaging unit 104 captures a face image of the legally authorized person in the vicinity of the specific area to acquire face image data. Further, the face image data of the authorized person acquired by the registration photographing unit 104 is stored in the attendee information storage unit 102.

  Here, “the vicinity of (a specific area)” corresponds to, for example, the vicinity of the event hall, the same building as the event hall, or the like. Compared to the conventional case where the purchaser himself photographs and uploads a face picture when purchasing a ticket etc., the quality of the face image can be easily secured, and the time and effort for the purchaser to retake many times can be saved. In addition, by performing registration of the face image in the vicinity of the place where face authentication is performed or at the same place, shooting conditions (illuminance etc.) at the time of face image registration and face authentication are the same, so more accurate face authentication is performed. It is possible.

  Further, specifically, the registration photographing unit 104 can be realized by, for example, a single face image photographing apparatus or a face image photographing camera function provided in a certain apparatus. Further, the registration photographing unit 104 may be installed near (for example, adjacent to) the authentication photographing unit 106 described later, or may be installed integrally with the authentication photographing unit 106. Furthermore, the registration photographing unit 104 and the authentication photographing unit 106 may be configured as a single combined camera. Installation cost can be reduced when both are comprised by one common camera.

  More specifically, for example, when a participant who has previously performed an entry application procedure online visits the event site, he / she takes a face image of his / her face with the registration photographing apparatus (registration photographing unit 104) prior to the entrance start. Take a picture. The registration photographing unit 104 causes the attendee information storage unit 102 to store the photographed face image data of the participant. At this time, a link is made between user data such as the participant's name, address, and telephone number stored in advance in the attendee information storage unit 102 and the face image data of the participant acquired by the registration imaging unit 104. The user ID may be read at the time of photographing the registration face image in order to make the registration. For example, when a participant enters user data at an application site and performs an entry application procedure, the site is notified of a user ID, and the participant shoots a face image with a registration photographing apparatus (registration photographing unit 104) At the same time, the user ID may be input. The user ID may be downloaded by the applicant from the application site in the form of, for example, a two-dimensional code such as a QR code (registered trademark) or a bar code.

  In addition, before photographing the face image of the visitor in the registration photographing unit 104, the clerk may visually confirm whether the visitor is the person who has made the application in advance (ie, the clerk The applicant's information exists in the form of paper, electronic data, etc. at hand). For example, the clerk visually checks the identification card carried by the visitor, and the name, address, telephone number, etc. described in the identification card are stored in advance in the attendance information storage unit 102 It may be made to confirm whether the applicant's name, address, telephone number etc. match. In addition, it may be possible to visually check whether the face photograph attached to the identification card and the face of the visitor are the same person. Then, the face image of the visitor may be taken by the registration photographing unit 104 only when the two match. Thereby, while performing the person identification by face authentication while enforcing the conventional person identification method, while being able to perform smooth entrance, security can be improved. Conventionally, as a method of identity verification, identity verification is performed using a personal identification card for the participants who have visited the event site prior to the entrance start time, and a list on the participant's wrist is provided as proof that identity has been verified. There is also a method of putting on a band or giving a prescribed document, and visually checking the wristband or the document upon admission for admission. However, in such a method of identity verification, for example, by separating the wristband cleanly and passing it to the other person, it is possible for another person to join the wristband and wind it around the wrist, to make an unauthorized act such as impersonation or admission. there were. On the other hand, as in the present embodiment, after the clerk visually identifies the user, the user is allowed to register the face image, and when entering, the face image is used to perform face authentication. It is possible to prevent the

  The authentication photographing unit 106 photographs the person to be authenticated when entering the specific area. The authentication photographing unit 106 is installed near the entrance of a specific area such as an event hall, for example, and photographs the face of a person who is going to enter the specific area (person to be authenticated). The photographing may be performed by the authentication target person consciously turning the face toward the authentication photographing unit 106, or the authentication target person may not be particularly aware of a specific area (for example, near the entrance). ) May be done by walking. In addition, data of the captured face image is output to the matching unit 108.

  Further, as described above, the registration imaging unit 104 and the authentication imaging unit 106 may be separate imaging devices or the like, or may be an integrated or combined device / function. In any case, when the physical distance between the registration photographing unit 104 and the authentication photographing unit 106 is close or at the same position, the face image is photographed when photographing the face image for registration and for authentication. Since the shooting conditions (illumination etc.) at the time of shooting are almost the same, the accuracy of face authentication can be further enhanced and authentication errors can be reduced.

  The collation unit 108 collates the face image of the person to be authenticated taken by the photographing part for authentication 106 with the face image based on the face image data of the authorized person previously stored in the attendee information storage part 102. In addition, collation of a face image can be performed using a prior art. Further, determination of coincidence or non-coincidence of the two may be, for example, setting a certain threshold, and setting it as a collation result of “coincidence” when the coincidence rate of both is equal to or more than the threshold.

  Further, a plurality of pieces of face image data may be stored in the attendance information storage unit 102 for one legally authorized person. That is, the registration photographing unit 104 may register a plurality of face images of the visitors. As described above, by storing a plurality of face image data for one legally authorized person, for example, even when face authentication fails due to a certain face image, face authentication can be further performed by another face image. Since this becomes possible, there is an advantage such as improvement of the authentication rate.

  The issuing unit 110 issues information used in a specific area when the matching in the matching unit 108 is successful. For example, when the matching in the matching unit 108 is successful, the issuing unit 110 issues a seat ticket indicating a seat in a specific area such as an event site assigned to the person to be authenticated (entrant). Then, the certification target person can sit in his / her seat by receiving the issued seat ticket and entering the specific area. Usually, in a concert venue or the like, an admission ticket is issued to the applicant in advance (for example, at the time of application) in a paper base or in the form of a digital ticket. Then, the applicant must carry the admission ticket or store it on a portable terminal such as his own smartphone and visit the concert hall or the like. However, in the face authentication system of the present embodiment, if face authentication is successful, a seat ticket will be issued on the spot, so if the applicant comes home without preparing a ticket etc. Good.

  In addition, as a method of issuing information by the issuing unit 110, there are various methods such as printing output on a paper basis and transmitting information in the form of electronic data to a portable terminal of an attendee. The issuing method may be paper-based, may be in the form of electronic data, may be output by voice, or the like.

  The result output unit 112 outputs the collation result in the collation unit 108. More specifically, for example, when the matching result in the matching unit 108 is a failure result (a face does not match), the face image does not match the display (not shown) of the face authentication system 1. You may display a message to that effect. Further, for example, the collation result may be displayed on a computer (including a portable terminal such as a smart phone) for an attendant who is near the face authentication system 1. Then, if the verification result is unsuccessful, the clerk displays the face image of the authorized person stored in the attendee information storage unit 102 on the computer for the clerk, and the person to be authenticated actually visited It may be possible to make a visual comparison with the face. At this time, for example, the face image data of the authorized person stored in the attendee information storage unit 102 may be transmitted together with the collation result to the computer for the attendant, or the computer for the attendant may enter in advance. A copy of the face image data of the authorized person stored in the person information storage unit 102 may be stored.

  As mentioned above, although an example of composition of face recognition system 1 concerning this embodiment was explained, each above-mentioned composition may be constituted integrally (for example, as one device), and it is a separate device. It is also good. For example, the authentication photographing unit 106 and the issuing unit 110 are included in the face authentication apparatus installed near the entrance such as an event hall, and the attendee information storage unit 102, the collating unit 108, and the result output unit 112 May be provided in a server apparatus installed remotely, and the registration imaging unit 104 may be an imaging apparatus installed in the vicinity of the authentication imaging unit 106.

(Hardware configuration)
The face recognition system 1 described above can be realized by the same hardware configuration as a general computer device. FIG. 3 is a diagram showing an example of the hardware configuration of the face recognition system 1. The computer device 40 shown in FIG. 3 is, for example, a processor 41, a RAM 42, a ROM 43, a built-in hard disk drive 44, an external hard disk drive, a CD, a DVD, a USB memory, a memory stick, an SD card, etc. A memory 45, a communication interface 46 for communicating with other computer devices, an input / output user interface 47 (display, touch panel, keyboard, mouse, speaker, lamp, etc.) for the user to exchange data, and a camera 48 Prepare. For example, the processor 41 reads a program stored in advance in the hard disk drive 44, the ROM 43, the removable memory 45 or the like to a memory such as the RAM 42 and executes the function of each component of the face authentication system 1 according to the embodiment described above. Can be realized. The hardware configuration shown in FIG. 3 is merely an example, and the present invention is not limited to this. Further, each configuration of the computer device 40 may be integrally configured, or a part may be configured as another device.

(Processing flow)
4 and 5 are flowcharts showing an example of processing in the face recognition system according to the present embodiment.

(Processing flow: face image pre-registration)
FIG. 4 is a process flow regarding pre-registration of a face image.

  For example, when a participant who has previously applied for participation on the application site arrives at the event site on the day of the event, he / she first shows an ID card to a person in the event site. The clerk confirms whether the name, address, phone number, etc. described in the ID card matches the applicant's name, address, phone number, etc., stored in advance in the attendee information storage unit 102 ( Furthermore, the face photograph of the ID card and the face of the participant may be visually checked (step S102). If it is determined that the result of the visual inspection is the applicant itself, the fact may be input to the registration imaging unit 104. Then, the registration photographing unit 104 may be set to be capable of photographing under the condition that the input of the judgment result is received.

  When it is judged that the result of the visual inspection of the clerk is the applicant himself (Step S104: Yes), the registration photographing apparatus (the registration photographing unit 104) is valid before the entrance procedure by face authentication is started. The face image of the authorized person (applicant) is photographed (step S106). The face image data acquired by photographing is registered in the attendee information storage unit 102 (step S108).

  The photographing of the face image by the registration photographing device may be performed, for example, before the time set by the event organizer or the like in advance before the entrance start time. For example, crowding of the hall can be reduced by performing the face image registration before the scheduled time when the entrance process is started. In particular, when the registration photographing unit 104 and the authentication photographing unit 106 are located very close to each other (for example, when they are adjacent) or realized by the same camera device, immediately before or after the entrance start. If the face image registration process is being performed, the person who is trying to enter and the person who is going to perform the face image registration will gather at almost the same place, and there is a possibility that the venue will be crowded locally There is. In order to avoid such a situation, it is desirable that face image registration be performed by a time before the entrance start time.

(Processing flow: Face recognition admission)
FIG. 5 is a process flow regarding face authentication admission.

  First, for example, when the face authentication system 1 (or another device) detects that the person to be authenticated approaches within a predetermined range in the shooting direction of the authentication imaging unit 106 of the face authentication system 1, authentication is performed. The photographing unit 106 photographs the person to be authenticated (step S202).

  Next, the collation unit 108 collates the face image of the person to be authenticated taken by the photographing part for authentication 106 with the face image based on the face image data of the authorized person stored in the attendee information storage part 102. . (Step S204).

  If the verification in the verification unit 108 is a result of success (step S206: Yes), the issuing unit 110 issues information used in a specific area such as an event venue like a seat ticket (step S208). In addition, if the verification in the verification unit 108 is a failure result (step S206: No), for example, an alarm sound is emitted from the speaker, the light of the lamp blinks, etc. It may be made to notify nearby staff (step S210). In addition, the collation result may be transmitted to a portable terminal or the like carried by the clerk.

  The result output unit 112 outputs the collation result in the collation unit 108 (step S212). Note that the output of the collation result by the result output unit 112 (step S212) may be performed before step S208 and step S210.

  As described above, according to the face authentication system according to the present embodiment, it is not necessary for the attendee to upload and register his / her face picture at the time of ticket purchase, so to secure the quality of the face picture. There is no need to retake it over and over again. In addition, since the face photograph is taken in the vicinity of a specific area such as an event hall where face authentication is performed, the shooting conditions (illuminance etc.) at face image registration and at face authentication are the same, and authentication error is reduced. Face recognition can be performed.

  Although one embodiment of the present invention has been described above, it goes without saying that the present invention is not limited to the above-described embodiment, and may be implemented in various different forms within the scope of the technical idea thereof.

  For example, in the above embodiment, it is assumed that face image registration is performed near the event hall on the day of the event, but the present invention is not limited to this. For example, face image registration may be made in the vicinity of the event site by the day before the event. Thereby, congestion around the event hall on the day of the event can be reduced.

  Further, in the above embodiment, it is assumed that the visitor has performed the entry procedure in advance and the user data such as the name, the address, and the telephone number are recorded in the visitor information storage unit 102 in advance. But it is not limited to this. For example, there is no prior procedure, and the event participant may come to the event hall to perform face registration or the like.

  In addition, when a participant performs an application procedure for participation in an event in advance, a face image is also registered in the attendee information storage unit 102, and a face image is registered again in the vicinity of the event hall. It may be done. In this case, for example, when an attendant at the event venue performs identity verification with the visitor's identification card (for example, step S102), the face of the visitor himself / herself in addition to user data such as the name described in the identification card. Identity verification may be performed by comparing (and the face photograph attached to the identification card) with the face image registered in advance in the attendee information storage unit 102. Then, when the personal identification ends normally (for example, step S104: Yes), face authentication at the time of entrance may be performed using a face image photographed in the vicinity of the event hall. Thereby, identity verification can be performed with stronger security.

  Further, the scope of the present invention is not limited to the illustrated and described exemplary embodiments, but also includes all the embodiments that bring about the same effects as the object of the present invention. Further, the scope of the present invention is not limited to the combination of the features of the invention as defined by the claims, but can be defined by any desired combination of specific features of all the disclosed respective features. .
